OK, Silver Wizards, here's a funny wrinkle on this discussion Just imagine for a moment that you run a high school darkroom and at least once or twice a year a kid gets confused and dumps his (or her) tankful of fixer into the main Hypo Clear tank (or Perma Wash, in my case). Is this now-contaminated hypo clear/perma wash safe to run through my trusty old electrolytic X-Rite silver recovery unit?

My inclination is to add it to a batch of old fix and run it through rather than dump it down the drain.

Any advice?

Thanks in advance!
